Merge: libero native tasks + vendored HF assets (all 130, library-deletable)

Land the roboverse_pack.tasks.libero_native pack: run all 130 base LIBERO tasks
(scene + BDDL checker + OSC_POSE + render) with zero libero/robosuite import,
plus the migration that vendors each task as portable MJCF + 193 deduped shared
assets to HF RoboVerseOrg/roboverse_data (library-deletable). Additive: 20 new
files + the integration doc page. Verified: checker 130/130 bitwise, vendored
model fields 130/130 exact; tests 5/5; package imports without libero/robosuite.

+## Native MetaSim tasks — run (and delete) LIBERO
+
+The passthrough is bitwise but still *imports* `libero` / `robosuite`. The
+`roboverse_pack.tasks.libero_native` pack removes that dependency: a LIBERO task's
+**scene, success checker, controller and renderer** all run on `mujoco` + `numpy`.
+
+```python
+from roboverse_pack.tasks.libero_native.native_task import LiberoNativeTask
+
+# Resolves the portable MJCF + every mesh/texture from a local roboverse_data
+# clone, or downloads them from HF on demand. No `libero` / `robosuite` import.
+task = LiberoNativeTask.from_vendored("libero_object",
+                                      "pick_up_the_alphabet_soup_and_place_it_in_the_basket")

+task.success()               # ported BDDL goal checker (bitwise vs env._check_success)
+task.render()                # agentview RGB (geom-group matched to robosuite)
+task.step(action, grip)      # one OSC_POSE policy step (inlined controller)
+```
+
+What was ported, and how it stays 1:1:
+
+- **BDDL success checker** (`checker.py`) — every goal predicate reduced to a
+  MuJoCo-state test: `In`=oriented-box containment, `On`(object)=`check_ontop`
+  with exact `contact_geoms`, `On`(region-site)=`SiteObject.under` + parent
+  contact, `Open/Close/TurnOn/TurnOff`=articulated-joint thresholds (any/all).
+  Thresholds are recovered at export by probing the live object's own method, so
+  they are exactly faithful. **0 mismatch vs `env._check_success` on all 130.**
+- **OSC_POSE** (`osc.py`) — robosuite's operational-space control math inlined as
+  pure NumPy; per-step joint torque Δ = 1.8e-14 vs robosuite.
+- **Scene** — each task ships as a portable MJCF whose `file=` paths are vendored
+  asset relpaths; the loader re-applies robosuite's runtime fixture placement
+  (`body_pos/quat`, captured with `seed=0`) so the compiled model is
+  **field-for-field identical** (`max|Δ| = 0`).
+- **Render** — `mujoco.Renderer`'s geom-group mask is matched to robosuite's
+  offscreen `vopt` so a state-replay render is pixel-identical.
+
+### Vendored assets on HuggingFace (library-deletable)
+
+`scripts/native/migrate_libero_assets.py` exports all 130 tasks to a deduplicated
+tree (193 unique files / 265 MB — the Franka/arena meshes are shared by every
+task) published to the
+[`RoboVerseOrg/roboverse_data`](https://huggingface.co/datasets/RoboVerseOrg/roboverse_data/tree/main/libero)
+dataset under `libero/`:
+
+```
+libero/
+  manifest.json
+  assets/robosuite/<...>           # shared Franka / gripper / arena meshes
+  assets/libero/<...>              # per-scene objects, textures, meshes
+  tasks/<suite>/<task>.xml         # portable MJCF (file= are asset relpaths)
+  tasks/<suite>/<task>.goal.json   # resolved BDDL goal + OSC cfg + body_pos/quat
+```
+
+`_locator.py` resolves these from a local `roboverse_data` clone or HuggingFace on
+demand — so on a machine where `libero` and `robosuite` are **uninstalled**, the
+native task still loads and runs. Verified across all 130: model fields exact
+**130/130** (`max|Δ| = 0`), ported checker **130/130** (0 mismatch). Use
+`ROBOVERSE_DATA_DIR` to point at a shared cache.

+"""Ported LIBERO BDDL success checker — evaluates the goal with NO ``libero`` import.
+
+LIBERO checks task success by AND-ing the BDDL ``goal_state`` predicates against
+the live object states. This module reimplements the geometric primitives those
+predicates reduce to, reading them straight from a MuJoCo ``model``/``data`` pair
+(e.g. a MetaSim handler's physics). It is the piece that lets a LIBERO task be
+*evaluated* inside MetaSim without the upstream library.
+
+Predicate reduction (from ``libero/libero/envs``):
+
+* ``In(obj, region_site)`` — the region is a ``SiteObjectState`` whose
+  ``check_contact`` is always ``True`` (no dynamics for site objects), so it
+  reduces to ``in_box``: the object's body position lies inside the region site's
+  oriented box (``site_pos ± |site_mat @ site_half_size|``, lower z extended by
+  1 cm) — verbatim from ``objects/site_object.py::in_box``.
+* ``On(a, b)`` with ``b`` an object — ``ObjectState.check_ontop``: the surface ``b``
+  sits below the placed object ``a`` (``z[b] <= z[a]``) AND their ``contact_geoms``
+  touch AND ``||a.xy - b.xy|| < 0.03``.
+* ``On(a, b)`` with ``b`` a region site — ``SiteObjectState.check_ontop`` via
+  ``SiteObject.under``: ``a``'s body lies in the site's oriented box above its floor
+  (``size[2]-0.005 < (mat·(a-site))_z < size[2]+0.10`` and ``|·xy| < size[:2]``) AND
+  the region's parent object's ``contact_geoms`` touch ``a``'s. Contact uses the
+  exact robosuite ``contact_geoms`` sets (resolved to geom ids by the exporter).
+* ``Open/Close/TurnOn/TurnOff(obj)`` — articulated-joint predicates. LIBERO reads
+  each of the object's joint qpos and compares it to a per-object threshold
+  (``articulated_objects.py``); ``Open``/``TurnOn`` are satisfied if **any** joint
+  passes, ``Close``/``TurnOff`` only if **all** joints pass. The export step probes
+  the live object's own ``is_open``/``is_close``/``turn_on``/``turn_off`` method to
+  recover the exact ``(op, threshold)`` per object + the qpos addresses, so this
+  checker reduces the predicate to ``op(qpos[addr], thr)`` with no libero import.
+
+A goal is exported (see ``scripts/native/export_libero_task.py``) as a list of
+predicate dicts with model names already resolved, so this checker needs only the
+names + the MuJoCo state.
